.Thisinvention relatesto chairs andlis particularly directed tothefabrication and arrangement of achair structure'. wherein certairrpartsmay. be conveniently demountedforpurpos'esof; shipl ping;and'fstorage; `In the class of upholstered chairs, to which the presentstructure is largely applicable, the structures are rather massive andbulky and it is highly desirable, from the standpoint of interfittingthe chairs for saving space IUlduring shipping and storage, that thearms be removable. It is conventional practice to fully upholster thechairs at the plant and it will be observed that a problem ofconstruction is presented by demand for demountable arms since the armswhich necessarily include some upholstery, must be related and fitted tothe upholstered chair frame in such manner as not to dedestroy theembellished appearance of the finally assembled product nor require anyupholstering `operation after attachment of the arms.

It is, therefore, an object of the present invention to provide a chairin which the respective arms are demountable and quickly andconveniently attachable to the chair frame and firmly `n1ounted inposition of permanence and stability.

Other objects and certain advantages relate to the particular means forfirmly attaching the arms in place, which objects and advantages alongwith certain other objects and advantages `wil1 be more fully apparentfrom the description of the accompanying drawing, in which:

Figure 1 is a side elevation of the improved chair, a portion of thechair arm being broken away to illustrate a connection element for at-361.' Ltaching the same to the chair frame.

Figure 2 is a perspective View of an arm showing it removed from thechair.

Figure 3 is an enlarged sectional view taken on line 3 3, Figure 1,illustrating the attachment llgiof the support portion of the arm to theframe.

Figure 4 is a sectional View taken on line 4-4, Figure 1, illustratingthe connection of an arm attaching element to the frame.

The chair in which the present improvement is incorporated is of thattype having a unitary seat and back wherein the upholstery completelycovers the unitary structure. This unit is mounted upon any type ofsupport means disposed on a base. The arms are furnished as unitsinclud- 5ll 'ing a support or vertical post and the arm proper, theseunits being shipped from the factory in assembled form with theupholstery in place and the attaching elements included in the armunits. Referring to the drawing, the unitary seat and v.back isgenerally indicated at 10. The back 11 is inclined in the-usuarfashiomeiauve to. theseat 12. The-cushions may be removable or?built into the unitary' framerstructure.' The generalf frame work oftheunitary seatfand back is' of wood asY disclosed'andis entirely coveredA'witl'r upholstery and cloth. This unit is supported on a well knownform of spring structure V13 permitting rocking of the unitary seat andback, the spring structure being mounted on a base 14.

It will, of course, be understood that the present demountable armconstruction can be conveniently applied to any type of chair and therocking chair type is only disclosed as one environment or example ofutility of the invention.

Intermediate of the length of the back 11 of the chair and at each side,attaching elements 15 are secured thereto. Each attaching elementconsists of a body portion of a contour fitting the style of the chairand mounted upon a dowel pin 16 protruding from the side of the chairbeing glued thereon after the usual dowel connection practice. A nail1'7 is driven outwardly through the frame member of the chair into theattaching element to prevent rotation on the dowel pin. Each attachingelement includes a forwardly extending dowel pin 18. The dowel pins 18do not extend beyond the forward face of the chair back and are apermanent fixed part of the chair not included in the arm units hereindescribed.

Each chair arm unit includes an arm proper or rest 19 which has itsforward end supported on an arm post or support element 20, these partsbeing curved to lit the style of the chair. The arm includes upholstery19@ arranged so as not to interfere with the detachability of the armunit.

The arm support element includes a lower or attaching portion having adowel pin 21 extending outwardly therefrom and toward the chair when inposition. At diametrically opposite sides of the dowel pin, attachingscrews 22 are mounted beingscrewed into the chair arm support andincluded as a part of the arm unit. The chair framev at each sidethereof includes drilled holes 23 in its side rails 24 positioned tocorrespond to the positions of the dowel pin and screws and fitting thesame, the screws, when in position, extending entirely through the siderails of the chair seat for the application of nuts 25.

It will be seen that when the arm units are removed, there is noprojection into the region or angle between the seat and back. For thisreason it is possible tonest the unitary seats and backs for shippingwith the under parts removed or in place.

In assembling or mounting the arm units, each one is shoved back on itsrespective dowel pin, there being a drilled hole 26 in the rear end ofeach arm engaging the particular dowel pin 18. The forward end of thearm unit and the lower end of the support is then moved toward the sideframe forcing the dowel pin 21 and screws 22 into their respectivedrilled holes, and the nuts 25 are thereupon applied by manipulationthrough the space beneath the chair structure.

Glue may be used on the dowel pins of the attaching element if desired,this, however, being arbitrary since the tightening of the forward'devices firmly anchors the arm units in position of stability. The dowelpins are spirally grooved for pocketing the glue and permitting theapplication of a greater quantity into the connection fora positivepermanent attachment. f Y

The unitary seat and back is completely covered with upholstery andcloth and the attaching elements may be readily secured in positionwithoutv disturbing the cloth covering. The demountable arm is alsoattachable without disarrangement of the upholstery or cloth or Withoutnecessitating removal or displacement thereof. The arm units are readilyand efciently applied to the chair by the dealer after shipment withoutthe use of glue or other attachment means which it is inconvenient forthe dealer to have and apply.

Having described my invention, I claim:

In a chair, a unitary upholstered and completely cloth covered seat andback, arm units including arm rests and supports, a fastening element ateach side of the back, said elements fastened over the cloth andupholstery and including studs projecting forwardly, said elements beingclear of the angle between the seat and back, the frests of said armsincluding sockets at their rear ends adapted to fit upon the respectivestuds, fastening elements extending inwardly in the llower end of eachsupport, the seat of said unitary seat and back including bores in itssides for receiving said fastening elements, whereby a chair is providedwhich is fully upholstered and which can be shipped stacked one withinthe other without interference by the arm attaching means and to whichthe arm rests may be attached after shipment without disturbing saidcloth covering and upholstery.
